I originally bought one for my gf but liked it so much a few months later I wanted one too. The mesh keeps me cooler and the ergonomics helps support my lower back when I have to sit for long durations.
It took only 5 days for the Staples to pull out of the seat. I'm well under the max weight limit. I was very surprised when it happened while I was sitting at my computer. Also the seat is kinda narrow and odd to sit on only mesh with out a cushion. Lastly there is rubber through out the mesh which grabs clothes skin and hair.
